Improvement in gang-plows

Lette/rs Patent No. 86,608, dated February 2, 1869.

IMPROVEMENT IN GANG-FLOWS.

The chedule referred to in these Letters P atent and making paxil; of the same.

To all whom it ma/y conce/m:

' axle, 1n order to show the mechanism more perfectly.

The peculiarity of my invention consists in raising and lowering the plows of a common gang-plow, in the manner described below, by means of foot and handlevers, in the manner described, in connection with certain toggleshaped links, embracing the bent axle and the foot of a certain lever conjointly, also, of a rotary motion given to the axle of the supportingwheels, produced by another lever, E, which is iirmly secured to the same, thereby gauging the plows to any depth required.

The operation of the device is as follows: A

When the plows are low in the ground, and it being required to raise them ont, the handle C, iig. 2, is raised' up, thereby disengaging the teeth on its lower edge from the bent lever B. The lever Bis now pushed toward the team, which, by a short arm on the under side, brings the link G almost perpendicular over the axle, thereby raising -the plows out of the ground.

In order to lower the plows into the ground, exactly the reverse has to be done, viz, pull the lever B toward you as you sit on the seat Q; and it will beseen that the axle is held in place by the two links F and G, in conjunction with the lever B.

' The axle It is bent atv one end, in order to eccentricate the left or near wheel.

The plows are still further lowered by grasping the lever E, after unhooking the latch I, and pulling it toward the seat Q, this allowing the belly of the axle tosettle down as` the bend becomes vertical instead of horizontal. l

Another' feature of the improvement is the entire freedom of the plows .to -seek their own draught-line, as they are hung and drawn by a clevis, as any ordinary di'auglitplow.

If the team raises a mound of earth, it does not afi'ect the plows, as they are entirely free to rise or fall with the, movements of the clevis N.

To this clevis N are 4securely attached a foot-levend), and a hand-lever, A. y

Shouldthe plewnianA wish .the plows togo deeper* for any cause, he presses his weight on the foot-lever D, which is exactly equivalent to riding on the beam Vof a common plow; or, by pushing the handle A forward, throws the plow out of the ground, until the temporary diiiiculty may be passed.

The plow-frames K have a bolt about midway their length, which travels in a slot, L, seen in figs. 2 and 3, and goes forward and back, as the tongue M rises and falls, in going over uneven ground.

There is a bar, H, on the edge of which are some notches, engaging with the level E,- holding the same in a similar manner as the piece G holds the lever B, wherever it may be desirable to adjust the plows P.

The check J is used to prevent the lever E from going too far back, and, when not plowing, the latch `I holdsit entirely out of ground.

It is thought that the parts above described :are irnprovements on known methods, are simple and easily made, and altogether form a novel device.

What I desire to claim by Letters Patent, is-

The levers A B C D E, the links G and F, (in which may be rotated the bent axle R,) the bent axle R, and the latch I, when used in the manner described, and for the purposes set forth.
